The lines of the form " alg: No test for cts1(cbc(aes))
you have the Crypto API testmgr enable (or rather not disabled would
be more accurate) so every
cryptographic algorithm except those specified in these messages was
tested with test
vectors from crypto/testmgr.c upon registration. If you don't seen
failure warnings, it works.
You can also check /proc/crypto for all the algorithm with ccree
listed as their driver and check
that their test passed.

tcrypt.ko is a rather crude developer tool. It has hard coded lists of
test for different algorithms that does
not take into account if some crypto algs are enagled in the build or
not. It's more of a stress test.
